Answer:
The correct answer is - 2Cu + 4HBr → 2H[CuBr2] + H2
Explanation:
Copper (Cu) and hydrobromic acid (HBr), which is a dissolved form of hydrogen bromide in the water, react and produce hydrogen dibromidocuprate (I) and hydrogen molecules.
The complete and balanced equation is -
2Cu + 4HBr → 2H[CuBr2] + H2
This reaction takes place in the medium of ester. Copper is in the suspension form in this reaction.
Thus, the correct answer is - 2Cu + 4HBr → 2H[CuBr2] + H2
Answer:
yes it did.
Explanation:
the product must have produced a smell therefore it created a gas. this means it was a chemical reaction
The statement "<span>For water to become a mechanical weathering agent through ice wedging, it needs to go through a cycle of freezing and thawing." is true</span>
Answer:
A Sink
Explanation:
Anything greater than 1g/cm3 will sink in water
In a mixture of gases, the total pressure is equivalent to the aggregate of all the partial pressures of the single element of the gas.
It can be written as 
= P₁ + P₂ + P₃ and so on.
The partial pressure will be:
Option A. 0. 31 atm
Pressure can be estimated by:
<u>PV = nRT</u>
Where,
And,
Solving finally we get,
Therefore, 0.31 atm is the partial pressure of the hydrogen gas.
